Just because a Pokemon is beaten by some other Pokemon does not prevent that Pokemon from ranking up.

Say, Mega Salamence is countered by Skarmory, but it would be nonsense to say it does not deserve S rank.

And as Awesomebob1 said, Arena Trap prevents Ferrothorn from switching in away. Dugtrio is a niche Pokemon that traps what the team needs. I'm not saying Dugtrio is a very good Pokemon, but I can say it has enough reasons to move up. I'll probably move it to B- due to relatively solid niche unlike those in C+.
